A MATHEMATICAL-MODEL ON A DESALINATION PROCESS

Mathematical models on the desalination of brackish water using EDR process are formulated. The product desalinated water variable is hypothesized as being dependent upon the following independent variables : total dissolved solids of the feed water, total dissolved solids of the product water, the rate of feed water, the temperature of feed water, the number of stages of membranes, and the energy consumption. The final model which is selected on statistical basis is considered appropriated for both prediction purposes and for the purpose of quantifying the separate effects of each significant variable upon the rate of production of desalted water variable. Results of the analysis are reported herein.
